I am driving and my lamp monitor comes on. No line signifying a specific spot for the light thats out. No words either. I hit a bump and EVERY light monitor light comes on. Tail lights, high beams, parking lamp, etc.

Give it a few seconds (normally when I hit another bump) and it all goes back to normal. No light monitor at all.

Any idea what this could be? I know it must be a loose/dirty connection but where do these lights all have a central connection at?

Sounds like the cluster is freaking out. See if you can find another at a JY and try it.

I've heard about several problems with lamp monitors. Someone with experience in your model year will likely answer your question and provide some diagnostic tips. Have you tried searching topics related to this yet?

does the DIC ever flicker or turn off?

Yes the digital interface has flickered to the point of turning off before. The last time it did that was about 4 months ago though. Today the front turn signal lamp popped on for 5 seconds.

Nothing much from searches.

There is nothing else that controls these codes besides the dash?
